Product Description

The Mylex AcceleRAID 352 controller is an Ultra 160 SCSI to a PCI dual

channel RAID controller with 64-bit, 33MHz PCI capability. The

AcceleRAID 352 supports two external Ultra 160 SCSI connectors, two

internal Ultra 160 SCSI connectors, and an optional battery backup module

(BBM). The AcceleRAID 352 controller provides the speed and

functionality required by high demand server platforms. AcceleRAID 352

achieves performance breakthroughs in PCI technology, eliminates storage

bottlenecks and delivers scalable performance. Enclosure management and

PCI Hot Plug are standard features.

Installation

This chapter describes:

• Before you begin

• Safety considerations

• Installation checklist

• Connectors, Jumpers, LED’s

• Controller installation

• SCSI cabling and termination

• SCSI IDs

• Limitations on mixing SCSI drive types

Mylex disk array controllers are designed to work in a variety of SCSI RAID

application environments. Certain configuration steps need to be performed

prior to installing the controller into a RAID environment. Each of the steps

described in this chapter are part of the installation process.

Before You Begin

2-2 AcceleRAID 352 Installation Guide

Before You Begin

Installing the AcceleRAID 352 Dual Channel RAID controller is no more

difficult than installing any 32-bit or 64-bit PCI adapter. The AcceleRAID

352 dual channel controller connects into any PCI slot (PCI 2.1 or 2.2

compliant) on the motherboard. Follow these steps and the installation

procedures in this chapter.

 WARNING

Working with the system covers off and power

applied to the system can result in shock and

serious injury.

This controller is furnished with a nonvolatile

RAM (NVRAM) chip that uses a sealed lithium

battery/crystal module. Replace the module only

with the same or equivalent type recommended by

the manufacturer.

Dispose of the used battery/crystal module

according to the manufacturer’s instructions.

Never incinerate a battery as it could explode and

cause serious injury.

1. Power off the system and disconnect the power cables before starting

the installation. Refer to the instructions provided in your system

documentation. Do not disconnect cables or power cords while system

power is on.

2. Read all of the instructions in this chapter completely before proceed-

ing. Follow the Notes, Cautions, and Warnings described in this manual

and marked on the equipment.

3. Follow electrostatic discharge (ESD) safe procedures. Use a grounded

wrist strap or ESD safe footwear, and work in an ESD safe area.

4. Perform a safety check of the installation before powering on the

system.

• Make sure that the cabling Pin 1 location is correct and that all

cables are firmly seated in the connectors.

• Make sure all SCSI conventions (cable type, cable length,

termination, etc.) are correct, see Table 2-5.

Installation

Manual No. 775051 2-3

Safety Considerations

Be sure to observe the following precautions before beginning the controller

installation procedure:

 Caution

Anti-static handling procedures are required. Leave

the controller in its anti-static bag until it is time to

plug the controller into the PCI slot. The use of a

grounded wrist strap and other ESD protective

measures are highly recommended.

 WARNING

Disconnect the system from the electrical wall

outlet before opening the system cabinet. Working

with the system covers off and power applied to the

system can result in shock and serious injury.

Installation Checklist

GET READY

☛ Note

It is recommended that you wear a grounded wrist

strap when working with hardware installation

procedures.

1. ____ Power off your computer system.

2. ____ Decide which available PCI slot will be used.

3. ____ Remove the plate from the I/O access port to the PCI slot.

4. ____ Remove the AcceleRAID 352 controller from the anti-static bag.

GET SET

5. ____ Plug the AcceleRAID 352 controller into a standard PCI slot

(PCI 2.1 or 2.2 compliant--if using hotplug feature, must be 2.2).

6. ____ Tighten the AcceleRAID 352 controller into the mounting

bracket.

7. ____ Connect the SCSI cable(s) from your drive(s) and/or device(s) to

the desired SCSI channel.

8. ____ Check SCSI termination for internal and/or external devices.

9. ____ Check disk drives. Be sure termination is set to the disabled

position on any disk drive(s) that will not be terminated. For more

information, see the documentation that accompanied the disk

drives.

10. ____ Set SCSI ID on the disk drive(s).

11. ____ Enable termination power on disk drive(s).

12. ____ Safety check the installation.

☛ Note

Review Figure 2-1 and Table 2-5 to get familiar with

the layout of the AcceleRAID 352 controller and the

Connectors, Jumpers, and LED descriptions.
